WILLIAM B. MORRIS, OF SAN FRANCISCO, CALIFORNIA.

RAILWAY-CROSSING BARRIER OR GATE.

SPECIFICATION forming part of Letters Patent No. 271,102, dated January 23, 1883.

Application filed April 18, 1882. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM B. MoRRIs, of the city and county of San Francisco, State of California, have invented an Improved Railway-Grossing Barrier or Gate; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a new and useful crossing barrier or gate for railwaycrossings and it consists in sundry details of construction,as hereinafter fully described, and specifically pointed out in the claims.

The object of my invention is to give notice at a point where unusual danger exists, and at the same time keep back those who might attempt to cross the track by placing an obstruction in the road.

Referring to the accompanying drawing, Figure l is a perspective view of myi'nvention.

Let A represent a series of posts placed at one side of the railway-track B.

Let (J represent a point where an ordinary wagon-road crosses the track. By the side of the road is a post, D,\vith an arm, 01, projecting over the track. From this arm depend pieces (1, by which the bell E is sustained. This bell has a shaft, 0, projecting from each side and journaled in the pieces (1. The shaft is provided with cranks e, as shown.

From the tops of posts A extend short arms a, with projecting pins a. Upon these pins are journaled stops 1), the lower ends of which are heavy enough to cause them to maintain a vertical position. Their upperends are formed into rings, through which a wirerope, F, passes. This rope is provided with small stopsf, impinging upon one side of the ringheads of stops 1). One end of the wire rope is attached to one of the cranks of the bell.

, Let G represent the locomotive of an approaching train. Upon the pilot is secured an upright beam, H, carrying in its top a rubber roller, 7b. This roller is at such a height that,

i as the engine passes, it will strike the lower ends of stops 1). The stops thus struck will have their upper ends thrown back, which, coming in contact with the stops fupon the wire rope, will pull said rope and cause the bell to give the alarm. Extending in the opposite direction from the crossing along the line similar posts, stops, and wire rope connecting with the other crank of the hell. In this set the position of the stops b andf with relation to each other is changed, so that they may be affected by atrain approaching in an opposite direction, but not by atrain which operated the first set. I

In the center of the track and cross-road is made apit, I,which is to be covered by a suitable box, having in its top a longitudinal slot, t'.

J are cross-bars in the track at the extremitending up through the slot 6, so that its center is elevated above the level of the road, and thus obstructs the passage, standing at such an angle and extending over such a length of track as to render the inclination of the levers so gradual as to yield without damage to the device when the locomotive comes in contact with the moving parts.

0 is a latch within the pit. This consistsofa strong strip pivoted at its middle. Its top is provided with a beveled stop, 0, and its lower end with a weight, 0. Upon the vertical bar L is a beveled stop, 1. \Vhen the lever K is depressed and the bar L pushed down, the stop I slips past the stop 0, and when below it the latter swings back and the bar is held down, thus keeping the lever K down out of the way.

In the ground is laid agas-pipe,P,in which a strong wire, 9, is carried. One end of this wire is attached to the lower end of the latch O. The outer end of the gas-pipe is enlarged to form a box, Q, in which is a pulley, q. The wire passes under this pulley and up beside one of the posts A to its top, thence over an- 5 other pulley, r, to the main wire rope F, to which it is joined at a point where it may be affected by the first stop 1). Another wire, 19, is attached to the top of the latch O, and extends through a gas-pipe in the opposite direction, and is similarly conducted to the main wire rope upon the other side of the cross-rod. When the approaching train strikes the first stop, and at the same time that it affects the main rope to ring bell, it afiects the wire 19, which draws upon the latch O and causes it to release the bar L, which is sprung up by the weight and the toggle-lever is elevated. When the engine reaches the cross-road it runs down the lever K and causes it to become reengaged with the latch O, by which means it is held down, so that it will present no obstruction after the train passes. As the engine meets the stop b upon the other side, they do not afiect the wire, as the stops f are on the wrong side for a train passing in that direction.

A lamp, B, may be placed upon the bar L.-

The stops may be placed at any safe distance from the cross-road by having wires sufficiently long, and thus warning may be given in ample time of the approaching train.

I am aware that all that portion of the apparatus hereinbefore described relating to the audible signal made by the bell is not new, and hence I make no claim thereto.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The toggle-lever K in the track andcrossroad, bar L, with its beveled stop I, lever M, and weight W, and the swing-latch'O, with its stop 0, in combination with the wires 19,- main wire ropes F, stops f and b, anda striker, B, upon the engine or car, substantially. as and for the purpose herein described.

2. The toggle-lever K, adapted to rise through a slot, 1', in the track, to obstruct a cross-road by means of the bar L, lever M, and weight W, in combination with the swinginglatch O, with its stop 0, the wires p in the gas-pipes P, pulleys q and 1', main wire ropes F, stopsf and b, and a striking device, H, upon the engine or car, substantially as herein described.

In witness whereof I have hereunto set my hand.

YVILLIAM B. MORRIS.
